Fault
Code
Fault Name In Panel
Description and Recommended Corrective Action
16
EARTH FAULT
Possible ground fault detected in the motor or motor cables. The drive
monitors for ground faults while the drive is running the motor and while the
motor is stopped. Detection is motor sensitive when the drive is not running
and can produce false positives. Possible corrections:
• Check for/correct faults in the input and output wiring.
• Verify the controller uses a recommended load reactor for long output
cable runs.
• A delta grounded input power supply and motor cables with high
capacitance may result in erroneous error reports during non-running.
18
THERM FAIL
Internal fault. The thermistor measuring the internal temperature of the drive
is open or shorted. Contact factory.
19
OPEX LINK
Internal fault. A communication related problem has been detected on the
fiber optic link between the control and OINT boards. Contact factory.
20
OPEX PWR
Internal fault. Exceptionally low voltage detected on the OINT power supply.
Contact factory.
21
CURR MEAS
Internal fault. Current measurement is out of range. Contact factory.
22
SUPPLY PHASE
Ripple voltage in the DC link is too high. Check for and correct:
• Missing mains phase
• Blown fuse
• Input wiring/connections
• High voltage unbalance on the input power supply
26
DRIVE ID
Internal fault. Configuration Block Drive ID is not valid. Contact factory.
27
CONFIG FILE
Internal configuration file has an error. Contact factory.
34
MOTOR PHASE
Fault in the motor circuit. One of the motor phases is lost.
Check for and correct:
• Motor fault
• Motor cable fault
• Internal fault
35
OUTP WIRING
Possible power wiring error detected. When drive is not running it monitors
for an improper connection between the drive input power and the drive
output. Check for and correct:
• Proper input wiring - line voltage is NOT connected to drive output.
• The fault can be erroneously declared if the input power is a delta
grounded system and motor cable capacitance is large.
36
INCOMPATIBLE SW
The drive cannot use the software. Internal fault. Contact factory.
37
CB OVERTEMP
Drive control board is overheated. The fault trip limit is 88ºC. Check for and
correct:
• Excessive ambient temperature
• Fan failure
• Obstructions in the air flow.
38
NO WATER/LOSS OF
PRIME
This fault is detected when the pump load on the motor is lower than ex-
pected. Check for and correct:
• Adequate well level or water supply
• Plugged suction screen
• Restriction in piping.
• Air bound pump.
• Deadheaded pump, pump running against a closed valve.
• Incorrect setting of motor parameters. Run the Start-Up Assistant and
verify motor settings.
NOTE: The controller will automatically restart after this fault is detected
when the No Water Restart Time set in the Start-Up Assistant expires.
